Structural and energetic factors play an important role in the development of a new generation of automobile exhaust catalysts containing CeO{sub 2} doped with ZrO{sub 2} and/or other rare earth oxides such as PrO{sub x}, Y{sub 2}O{sub 3}, and La{sub 2}O{sub 3}. These new catalysts possess high oxygen storage capacity, improved thermal stability, and enhanced catalytic properties. These properties are discussed.
